The nerve is equally unimaginative in its reaction to damage. In
principle, only two pathological changes are seen. Firstly axonal damage
results in Wallerian degeneration, a bead-like disruption of the peripheral
nerve that involves both the axon cylinder and the surrounding myelin (Figure
8). This is seen in diseases affecting the axons in the peripheral nerve,
or in anterior horn cell disease.
Wallerian degeneration seen in axonal damage
Secondly demyelination results in peripheral nerves with shortened internodes
or internodes with thinner myelin (figure 9). Remember the axon cylinder
in demyelinating diseases is fine and healthy.
A nerve fiber with shortened internodes that are hypomyelinated;
typical findings in demyelinating neuropathies.
